To all 'who'ntit may con-cam:

4l've it known that I, HUBERT Horaires, a citizen of the United States, residing at Maplewood, l\liss6i n'i, have invented a certain new and useful Improvement in Typeriting Machines, of which the following is a full, clear, and exact description, such as will en able others slrillcdlin t-he art to which it appertains t'o make and use the same, reference being had to the accompanying drawi ings, forming part of this specification, in Whichl Figure l is a side elevation of t-he platen carriage of a type writer the same being equipped -With my 'improved attachment. Fig. 2 is a plan view of the end of theplaten carriage and showing my improvedattachment in position thereon. Fig. 3 is an en-' larged section taken approximately on the lline 3-3 of Fig. 2. Fig. 4 is a vertical section taken on the line lr-4 of Fig. 3. Fig. 5 is a vertical section taken on the line 5-5 of Fig. 2. Fig. 6 is a diagrammatic view illustrating the position of a carbon copy sheet, a. carbon sheet, and a statement or bill on the platen,'and showing the positions of the sheets after the matter forming the body.

of the statement or bill' has been type written thereon. Fig. 7 is a diagrammatic view illustrating the positions of the carbon copy sheet, and the carbon sheet on the platen after the latter has been reversely rotated to permit-the removal of the statement. or bill. Fig. 8 is a diagrammaticviewsimilar to Fig. 7, and showing a second bill or statement applied to the carbon sheet and carbon copy sheet on the platen and ill ust-rating the position of the printed head ofthe bill or.

statement relative to the matter transferred or copiedonto the copy sheet from the first bill or statement. Fig. 9 is a diagrammatic view similar to Figs. 6,"7 and 8 and illustrating the position of a carbon copy sheet, the carbon sheet and the second bill or statement after the platen has been rotated so as to carry the heading of the second bill past the printing line or the point where the type strike against the outer'sheet carried b v said platen.

and a carbon copy sheet 'carried the platen andwhich carbonA copy sheet receives carbon copies o'f the matter recorded or type -written upon the successive bills or statements. A Y

invention isof particular.advantage inmaking out and recording bills and statcments vand by the use of the invention I am able to produce a condensed-billing'. record,

crc., a record or copyof a large number of bills upon a single record sheet, which latter after being filled is removed from the machine and. placed in a suitable holder such as a loose leaf` binder.

My invention consists in `an adjustable gageand suitable shifting Vmechanism applied vto the platen shaft, nd which gage and shifting mechanism provide vmeans whereby the platen can be quickly and accurately rotated backward vand forward a .predetermined distance vso as to take up the space occupied by theprinted heads of the bills or statements successively fed onto the platen, and thus the mattei' type written on the successive bills or statements will be closely written on the carbon copy sheet,

-thus producing a condensed carbon copy record by avoiding blank spaces upon the carbon copy sheet betweenithe matter transferred thereonto.

My. invention further consists in certain novelfeatures of construction' and arrangementg'of parts hereinafter more fully described and claimed.

Referring by numerals to the accompanying drawings 1 indicates the usual platen carriage, 2 the platen, 3 the platen shaft and 1 1 the usual ratchet wheel which is fixed on the platen shaft adjacent the end thereof.

Arranged to slide on the end of the platen shaft 3 which projects beyond the carriage l is a sleeve 5 which is slotted as designated by 6 to accommodate a pin 7 seated in ,the shaft 3, and this manner of mounting the sleeve 5 permits the same to slide lengthwise upon the platen shaft.` .and ,rotate therewith. Formed on or fixed to the inner end of this sleeve 6 is a pinion S and carried by the outer end of saidI sleeve is'a knob 9. An expansive coil spring 10 is positioned within the sleeve lbetwcen the outer end of the Fixed on the outer face'of the carriage.

ing for a shaft 14 on the inner end\ of which is formed a head 15 the same occupying the opening within the hub 12 and positioned on -the shaft 14 bet-Ween the sleeve 13 and the 10 head 15 is an expansive coil spring 16. The

shaft 14 rotates in and slides freely through4 the sleeve 13, and is operated by means of a knob 17 positioned on the outer end of said shaft and projecting from said shaft 1 5 adjacent the knob is an arm 18, whichcarries-an inwardly projecting pin 19. A' disk 20 is positioned on thesleeve 13 and is fixed in any suitable manner to said sleeve or to the hub 12 and foimed through said disk 20 adjacent the edge thereof is a circular row of apertures 21, which latter correspond in 'number to the number of line spaces on the platen.

AMounted for rotation on the hub 12 is a gear wheel 22 with which the pinion 8 is adapted to engage and fixed to the outer face of this gear wheel is a disk 23 the outcx'- edge off which covers the outer faces of the teeth of the gear wheel 22, and formed in the edge 30 -of this disk 23 is a curved notch 24 the depth of which is equal to the depth of the teeth of the gear wheel 22. Seated in thisdisk 23 and projecting outward from and in the path of travel of the outer end of the arm 18 is a pin 25. This pin 25 projects through the gear wheel 22 and into a concentric groove 26 -fogmed on the inner face of the gear wheel 22. Projecting'from the face of the disk 11 into this groovej26and into the path 40 of 'travel of'the pin 25 is a stop 1n the form of a pin 27. An annular recess 28 is formed in the inner face of the gear wheel 22 and occupying said recess is a spiral spring 29, one end of which is. attached to the gear \wheel 22, and the inner end being fixed to gear Wheel 22 in such a manner that when said gear Wheel is rotated so as to carry the pin A25 a'w'ay from the stop 27 said spring will be wound upon the hub 12,'and when said gear Wheel is released the power .stored in the spring will return said gear wheel to its normal position witlrthe pin 25 against the stop 27 As hereinbefore ,described my invention is particularly adapted for use in getting ont a large number of bills or' statements and where it isdesired to make :1 condensed -recrd ofthe matter type written on the billsandstatements said record being in the form'ofl long sheet which when filled is removed fro'm' the 'machine -and positioned in l1 Suitable binder. Before beginning the work lof xiiakingout the bills or statements the operator asc'ei'tains the number of line A-the hub 12; This spring is arranged on the '.:spaces taken up by the printed heading of the bill or statemept, and assuming the num-4. ber of line spaces to be seventeen the operatoi' engages the knob 17 drawing the saine outward to disengage the pin 19 from the one of the apertures 21' in which it has been seated and then rotates the .shaft 14 to bring 'the pin'19 into position where it can be engaged in the seventeenth aperture from the aperture immediately adjacent the pin 25 when the saine is in itsnorinal position, as

seen in Fig. 1. The operator now engages the knob 9, pushesinwardly oii the same, thereby moving the sleei'e 5 and pinion S inward and bringing said lpinion into engagement wit-li the gear Wheel 22. The

operator now rotates the knob 9 and parts carried thereby, and t-he pinion S'ineshing;

with the gear wheel 22 rotates the same until the pin 25 engages against the arm 18, and

thus the platen is reversely rotated a distance of 17 line spaces. The operator now places.v

the carbon copyslieet, the carbon sheet and the first bill` `or statement upon the platen,

and engaging the knob 9 rotates the saine in l a direction reverse to Vthe direction in which said knob was previously rotated unt-1l the pin 25 on the gear wheel 22 is brought into engagement with the stop 27, whereby the parts are placed in normalposition, when the pinion 8 may move away from the gear 22 through the notch 24,'and the sheets of paperon said platen are fed into-the inachine a distance of Yseventeen line spaces, thus bringing the blank spaces on the bill or statement in position to receive the first line of type Written matter forming the body et .the bill or statement. After the matter forming the body of the first bill or statement is type Written the operator engages the knob, pushes the same inwardly until the pinion 8 engages the teeth of the gear wheel 22, and then rotatesthe knob 9 in such a n ianner as to turn the platen backward until the pin 25 engages against the arm 1 8, thus the platen is turned backward `a distance of seventeen line spaces, and is therefore, set to receive the next bill or statement. If the printed matter of the first bill or statement is in excess of seventeen printed lines then the operator to remove the first bill or statement 'engages the proper lever to manipulate the feed Wheels which bear against the under side of the platen, and the first bill or statement can now be' withdrawn from the machine leaving the'carbon sheet and the carbon copy sheet on the platen.

A second bill orstatement is now placed against the carbon sheet Withthe top edge `of said/bill or statement against the .feed

roller engaging against the platen and when so positioned. the printed heading of -the second bill or` statement overlies the type written matter transferred from the first bill onto the carbon copy sheet, and the ttl) Athe carbon sheet and the carbon copy sheet are fed into the machine around the platen thereof. During this feeding in movementthe pinion 8 drives the gear wheel 22 and plate 23 carried thereby, and when the pin i5 carried by said plate lrengages against they into the machine and around the platen a dis tance of seventeen lines spaces, which is the equivalent of the space occupied by the printed heading of the bill or statement, and thus the blank space. ot' the second bill or statement is brought into position to receive the first line'of the matter lobe type written on. said second 'bill or statement, and which type written matter will be recorded by means of the carbon sheeton the carbon copy sheetl immediately adjacent the matter recorded on said carbon copy sheet at `the time the irst bill or statenient was type written. This procedure is carried out with the succeeding bills or statements, and thus the type written matter forming the bodies of said bills or statements is recorded in condensed form upon the carbon copy sheet, that. is, the type written matter of one hill will closely follow the typewritten matt-r of the preceding; bill on the carbon copy sheet and by reversely rotating t-he platen each time a bill or statement is removed from the machine and lapping over the printed heading 'of the succeeding bill or statement upon the carbon copy of the body of the preceding bill or statement the spaces corresponding to the printed headings o f the bills 4or statements are entirely eliminated from the carbon copy sheet.

The arm 18 forms a gage to stop the backward rotation of the platen and when the platen is rotated forward for effecting the feeding in of the succeeding bills or statements the pin 25 carried by the gear wheel 22 engages against the stop 27, and when the partsaie so positioned thecurved notch 1n the edge of the disk is in position to permit. the pinion 8 to. move outward and when this action takes place thecperator knows that the space on the bill or statement is in proper position to receive the first line of type written matter forming the body of the bill or statement.. When the pinion 8 is moved inward to engage the gear wheel 22 and said pinion is rotated' slightly by nanipf\v ulating the knob 9' said gear wheelwill be locked or held in engagement with 'the gear wheel 22 for the reason that the teeth of the pinion 8 are behind the edge of tlie disk 23,A and the parts will be thus held in operative relation until the platen is-elevated to disengage the pinion 8 fronrthe gea-r Wheel 22 or until the platen is rotated in a-forward direction which finally brings the notch 24 into such position asto permit the pinion 8 to move outward by reason of theexpansive fthe arrows b and c represents Vthe' tvpe written matter forming. the body ofthe first bill or statement. arm 1S the second bill will have been moved Fig. 7 diagrannnatically illustrates the platen rotated in a reverse-direction far enough to permit the first bill or statement to be removed and the spaces between the arrows b and c represent the type written body of the first bill which is transferred by the carbon sheet onto the carbon copy or record sheet.

In F ig. 8 the second bill or statement -is shown applied to the platen 'with the printed heading of said second bill or statement covering or overlying the space corresponding to'the type written mattei' forming the body of the first bill and transferred to the carbon copy or record sheet.

In Fig. 9 the second bill or statement is shown as being fed into the machine a distance corresponding to the printed heading of said second bill or statement and the distance of .feeding in movement corresponds as hereinbefore described to the position of the arm 18 relative to the normal position of the pin 25.

My improved adjustment is comparatively simple, is easily manipulated, can be advantageously employed in connection with nearly all forms of type writers and billing machines and provides means whereby much time and labor are saved in the writing of the bills or statements.

The carbon copy or record of the bills or statements is of condensed form, thatis, with the type Written matter forming the body of each bill closely following 'the type Written matter forming the body of the preceding bill and by providing the adjustable gage or stop arm 18, the succeeding bills or written line forming thebody of the bill of' statement.
